Network security access control method and system based on the pre-shared key

摘要

A method and system for pre-shared-key-based network access control are disclosed. The method includes the following steps: 1) security policy negotiation is implemented between a REQuester(REQ) and Authentication Access Controller(AAC); 2) identity authentication and uni-cast key negotiation are implemented between REQ and AAC; 3) a group-cast key is notified between REQ and AAC. Applying the method and system, rapid bidirectional authentication can be implemented between a user and network.
